Tumor Regression Following Engineered Polyomavirus-Specific T Cell Therapy in Immune Checkpoint Inhibitor-Refractory Merkel Cell Carcinoma.

Although immune check-point inhibitors (CPIs) revolutionized treatment of Merkel cell carcinoma (MCC), patients with CPI-refractory MCC lack effective therapy. More than 80% of MCC express T-antigens encoded by Merkel cell polyomavirus, which is an ideal target for T-cell receptor (TCR)-based immunotherapy. However, MCC often repress HLA expression, requiring additional strategies to reverse the downregulation for allowing T cells to recognize their targets.

A facile strategy to prepare ZSM-5-based composites with enhanced light olefin selectivity and stability in the HTO process.

In this study, the influence of different ZSM-5 composite materials (ASA, γ-alumina, η-AlO, SiO, and attapulgite) and their performance in the -hexane catalytic cracking process in a fixed bed microreactor at 550 °C under atmospheric pressure was studied. XRD, FT-IR spectroscopy, NH-TPD, BET, FE-SEM, and TG analyses were performed to characterize the catalysts. The result of the -hexane to olefin process indicated that the A2 catalyst (γ-alumina composition with ZSM-5) showed the highest conversion of 98.

The effects of spaced transcranial Direct Current Stimulation combined with conventional dysphagia therapy in Parkinson's disease: A case report.

Parkinson's disease (PD) is a neurodegenerative disease of the central nervous system that is characterized by a set of motor and non-motor symptoms. Impaired swallowing or dysphagia is one relatively common motor symptom in patients with PD. We investigated whether neuroplasticity induction by spaced transcranial Direct Current Stimulation (tDCS) combined with conventional swallowing therapy leads to long-lasting effects on swallowing ability in patients with PD.

Clinical and paraclinical evaluation of partial nephrectomy using laparoscopy and open surgery in dogs: new suturing technique.

Partial nephrectomy, using open surgery or laparoscopy, is a standard surgical approach to treat renal disorders. The objective of this study was to compare and evaluate the feasibility and safety of laparoscopic partial nephrectomy using figure eight ligation technique. Mixed-breed dogs were randomly dedicated for partial nephrectomy using laparoscopy (n=6) and open surgery (n=6).

Comparison between two portal laparoscopy and open surgery for ovariectomy in dogs.

Ovariectomy (OVE) is a routine surgical procedure for neutering in small animal practice. Laparoscopy is a new surgical technique which contains advantages such as less trauma, smaller incision and excellent visualization than traditional open surgery. The present study was conducted to examine the feasibility and safety of laparoscopic procedure through two portal comparing with the conventional open surgery for OVE in healthy female bitches (n=16).
